CCS811 TVOC Air Quality Gas Sensor

Fr25,000

The CCS811 Air Quality Sensor Breakout Board is a digital gas sensor that senses a wide range of Total Volatile Organic Compounds (TVOCs) along with equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. The sensor can be used for monitoring Indoor Air Quality. The system can be used with a microcontroller unit (MCU), which includes an Analog-to-Digital converter (ADC) & an I²C interface.

Example Code (ESP32 / Arduino)

You’ll need the Adafruit CCS811 library. Install it via the Arduino Library Manager.

#include "Adafruit_CCS811.h"

Adafruit_CCS811 ccs;

void setup() {
Serial.begin(115200);

Serial.println(“CCS811 test”);

if(!ccs.begin()){
Serial.println(“Failed to start sensor! Please check your wiring.”);
while(1);
}

// Wait for the sensor to be ready
while(!ccs.available());
}

void loop() {
if(ccs.available()){
if(!ccs.readData()){
Serial.print(“CO2: “);
Serial.print(ccs.geteCO2());
Serial.print(“ppm, TVOC: “);
Serial.println(ccs.getTVOC());
}
else{
Serial.println(“ERROR!”);
while(1);
}
}
delay(500);
}
